You’re Probably More Likeable Than You Think
Researchers from Harvard and Cornell ran a series of experiments in which two people, meet for the first time and then rate their own and each others conversational performance. They found people consistently rated their conversation partner as more likable and enjoyable to talk to than they rated themselves.
Shy participants were especially prone to thinking this way, but it happened across most personality types. There was also evidence that the misconception persists beyond just the first interaction, potentially lasting months or even longer.
Study authors say the findings show people tend to be harder on themselves than they are on new acquaintances.
